CHARLES XVHITE, OF BALTIMORE, MARYLAND, ASSIGNOR OF ONE-HALF TO MICHAELHOLZMAN, OF SAME PLACE.

EMBROIDERY-CUTTING MACHINE.

FPECIPICATIQN forming part of Letters Patent No. 320,031, dated June 16,1885.

Application filed March 27, 1884. (No model.)

in (LZZ whom, it may concern.-

Beitknown that 1, CHARLES WHITE, acitizen of the United States, residingat Baltimore, in the county of Baltimore and State of Maryland, haveinvented certain new and useful Improvements in EmbroideryCuttingMachines, of which the following is a speciiication, reference being hadtherein to the accompanying drawings.

The object of my invention is to provide a movable knife which isadapted to separate the goods on a line with the outer edge of theembroider. I attain this object by mechanism illustrated in theaccompanying drawings,

:5 in which- Figure l isa top view with parts removed; Fig. 2, alongitudinal section; Fig. 3, front end view; Fig. 4, an end viewshowing position of belt-pulleys; Fig. 5, detail view of knife, showinggoods partly cut; Fig. 6, same as Fig 5, with goods removed; Figs. 7 and8, section views of Figs. 5 and 6; Fig. 9, a detail view showing methodof cutting; Figs. 10 and 11, views showing modifications in which anendless band is used, and Figs. .12 and 13 a modification in which theknife reciprocates.

Similar letters refer to similar parts throughout the several views.

The bed-plate A is supported by projecting o legs a, which are securedto a frame or table of any suitable kind.

From the under surface of the plate A project hangers b and Z), whichform bearings through which the shafts C and 0 pass. On the ends of saidshafts are rubber sleeves c c, which engage with each other and form thefeeding device.

To the opposite end of the shaft 0 is attached the driving-pulley D,which contains two grooves, one being occupied by thedrivingbelt, theother by the belt d, which passes over the pulley c to the idle -pulleye, thence to the pulley e" on the spindle f from which it returns to thedriving-pulley D by pass- 5 ing over a second idle-pulley e, the beltbeing crossed between the pulleys e on spindle f, and the idlers e and cto move or rotate the knifeF in the proper direction in relation to themovement of the goods while being cut. The spindlef runs in the bearings91 between which is placed the pulley (F, the lower endof the spindlecarrying the ci'ltting-knile F, the cutting-edge of which moves in aplane parallel to that traversed by the goods, part of which (as it iscut) passing over the knife F, and the other part passing under to thefeed-rollers c c, which draw the material forward.

The knife F rotates in a circular opening in the bed-plate A, providedwith a slot, g, at one side to allow the goods to pass downward Go tothe feed-rollers c c. On the side opposite to the slot gof the circularopening is a semi annular elevation, g (see detail Fig. 6,) the heightof which regulates the distance from the outer embroidered edge to wherethe goods are separated. The nearer the upper surface of the projectiony is to the surface of the knife plane the closer the material ill becut to the embroidery, or vice versa.

The semicircular plate h is pivoted at one end to the bed-plate A, whichpermits it to be moved to and from the knife F, whose function is toprevent the goods from puckering as they are cut, and its position is,when operating, close to the edge of the knife, as seen in Fig. 5.

The material is held in its place by the guide i, supported on the rod2", which passes through the supportn, and has an inward and outwardmovement to accommodate the dif- 8o fercnt size embroidery, and when setin the proper position is there held by means of the thumb-screw Theshaft I runs in bearings Z Z, suspended from the bed-plate A, and isprovided at one 9' end with the pulleye, by which itis driven by thebelt d, the other end having aslot, m, in which the cut goods areinserted to be wound into a roll as they pass from the feed-rollers c c.The shaft I and its attachments are not 0 essential to the cuttingdevice, and may be dispensed with, as its functions are only tofacilitate the handling of the goods after they are out.

In operating the machiuethe guide i is raised 5 and the plate h thrownback, permitting the goods to be placed in position, (a few inches ofwhich-are previously cut by hand,) the end containing the embroiderybeing passed over the knife F, and the other part being passed throughthe shot to the feedrollers c c, thence to the winding-roller or shaftI, and placed in the slot m. Theguide z'is then placed on the goods withits guiding-surface 2' bearing against the outer embroidered edge, 1),and the plate It moved in or placed around the knife F, the embroiderybeing placed in relation to the knife sothat the inner angles 19 of thescallops will just pass within the periphery of the knife F. As thegoods are moved forward,the section containing the embroidery is heldup, while the other section is drawn down, thus exposing only thatportion of the fabric which is in close proximity with the embroidery tothe knifes cuttingedge. The knifes cutting-edge moving in a planeparallel with the fabric, any regular or irregular line of embroiderymay be out by this arrangement.

As the gist of my invention is to have the cutting-edge of the knifemoving in a plane parallel to that of the surface which supports thefabric, 1 show modifications, which are illustrated in Figs. 10 and 11,in which an endless band, F, is arranged to run over the wheels B and Bwith its cutting-edge moving in a plane parallel to the surface of thefabric-supporting surface; with the wheel 13*, attached to the shaftf,which is provided with the pulley D, by which it is driven, and a bevelgearwheel, h, that engages with a similar wheel on theshaft O, whichoperates the feed-rollers c; and, as shown in Figs; 12 and 13, areciprocating knife, F, is arranged, likewise, that it will perform thesame function, and which is operated by the connectingrod 1L attached toa crank on the shaft f.

Having fully described my invention what I claim,and wish to secure byLetters Patent,is

1. In a machine for trimming embroidered fabrics, the knife F, incombination with a guiding or supporting surface 9 which is parallel tothe plane traversed by the cutting-edge of the knife, for the purpose asherein specified.

2. The combination of the knife F, the sur- 5 face 9 parallel to theplane traversed by the knifes cutting-edge, and the feed-rollers c c, asherein set forth.

3. The combination of the knife F, the surface g parallel to the planetraversed by the cutting-edge of the knife, and the plate h, for thepurpose as herein set forth. v

4. In an embroidery-trimming machine, the combination of the knife F,the guide or supporting surface 9 and the slot or opening 9, the wholebeing arranged to permit that portion of the fabric that is cut from theembroidery to pass on one side of the knife and the embroidered sectionto pass on the other side, as hereinspeoified.

In testimony whereof I affix my signature in presence of two witnesses.
